Warm and citrusy at the same time, coriander seed is enjoyed in curries and chili, cookies and cakes. A sister to cilantro--both come from the same plant--coriander seed has a lovely, fragrant aroma once ripened, while cilantro is often described as foetid.

Botanical name: Coriandrum sativum L.

For a citrus note, add a sprinkle or two of coriander to chicken or egg salad.
